<p>Real time systems, used in most of the day-to-day applications, require time critical exection of tasks. Worst Case Execution Time Analysis (WCET) is performed to ensure the upper bound on the time they can take to execute. This work aims to perform a static analysis of the industry standard code segments to provide valuable information to aid in choosing the right apporach towards WCET analysis. Any code segment can be analyzed syntactically, to gain some insights to the effects that a particular coding syntax format may have. With focus on the functions and looping statements, vaulable information regarding the code segments inspected can be obtained. For this purpose, the code segments from CC systems, Vasteras , were inspected. Scope graphs generated by SWEET, the Swedish Execution Time tool were used extensively to aid this work. It was found that syntactical analysis could be performed effectively for the code segments that were analysed as a part of this task.</p>

Cristallogénèse de CdTe : In par T.H.M. (programme EURECA) et de CdTe : V photorefractif par Bridgman : caractérisation physico-chimiques et optiques, influence de la gravité sur l'hydrodynamique de la phase fluideBerteloot-Mazoyer, Valérie 01 September 1995 (has links) (PDF)
Pour étudier l'influence de la gravité sur la croissance par T.H.M. du semi-conducteur CdTe dopé indium (programme EURECA), nous avons effectué une analyse comparative d'expérience spatiales et terrestres, complétée par une simulation numérique de l'hydrodynamique de la phase fluide utilisant un code 3D. Notre deuxième objectif a été de prépérer des monocristaux de CdTe dopé vanadium par la technique Bridgman présentant de bonnes propriérés photoréfractives. Pour une meilleure compréhension du mécanisme de l'effet photoréfractif, les matériaux ont été caractérisés par R.P.E., D.C.M. et P.I.C.T.S. afin de déterminer le degré de valence de V et la signature des niveaux vanadium dans la bande interdite. Des mesures optiques (absorption, photoconductivité...) et d'effet photoréfractif ont été effectuées. Enfin, pour évaluer la pertinence spatiale de cette croissance, nous avons étudié par simulation numérique l'influence de la gravité sur la configuration hydrodynamique de la phase fluide.
